140DDI84100 Schneider Relay Module
140DDI84100 is a DC discrete input module launched by Schneider Electric, belonging to the Modicon Quantum automation platform product. The module has 16 discrete input points, divided into 8 channels, which can be connected to field devices such as switches and sensors that can output digital signals. Each input channel can receive a voltage signal of 10-60V DC and is compatible with various DC voltage sensors and devices. For source type (PNP) and drain type (NPN) sensors, the module can be flexibly adapted through its sink/source capability; The module adopts electrical isolation technology, with isolation barriers set between the input side and internal circuits. The isolation voltage between each channel and the bus is 2500Vrms DC, and the isolation voltage between groups is 700Vrms DC, which can effectively suppress common mode interference and surge voltage; The module is equipped with LED status indicator lights for each input channel. When a signal is input to a certain input channel and correctly recognized by the module, the corresponding LED light will light up in green to facilitate operators to intuitively understand the input status of each channel; The module encodes and processes the input signal, converts it into digital form, communicates with other modules of the PLC through the backplane bus, and transmits the collected input signal status data to the CPU. In some cases, it may be equipped with communication interfaces such as Modbus RTU to facilitate connection and data exchange with other devices that support corresponding communication protocols. It can achieve remote monitoring, parameter setting, and fault diagnosis functions, facilitate system integration and management, and is widely used in industrial automation control systems.
